Lestes nigriceps Fraser, 1924 was described from a male (later the lectotype) and two non-conspecific females collected in 1922 at Pusa, Bihar State, India, and has never been reported since. In June 2018 a population of L. nigriceps was unexpectedly found in eastern Cambodia, Mondulkiri Province. The Cambodian males, their variation and, for the first time, the true female of L. nigriceps is described.
黑首环裳蜻(Lestes nigriceps Fraser,1924)依据1922年在印度比哈尔邦普萨采集的1只雄性标本(后为选模标本)和2只非同种雌性标本进行描述,此后再无报道。2018年6月,在柬埔寨东部的蒙多基里省意外发现了黑首环裳蜻种群。本文描述了柬埔寨的雄性个体、其变异情况,以及首次报道的黑首环裳蜻的真正雌性个体。
